beamwidth
The width (or the angle) of a beam of radiation
beamwidth
The width of the sent beam, discounting sidelobes, measured in degrees
beamwidth
A measure of the ability of an antenna to focus signal energy towards a particular direction in space (e g towards the satellite for a ground-based transmitting antenna), or to collect signal energy from a particular direction in space (e g from the satellite for a ground-based receiving antenna) The beamwidth is measured in a plane containing the direction of maximum signal strength It is usually expressed as the angular separation between the two directions in which the signal strength is reduced to one-half of the maximum value (the -3 db half-power points)
beamwidth
The angle in degrees over which a directive antenna will provide a gain within 3 dB of the value in the direction of maximum gain
beamwidth
The angle of signal coverage provided by a radio Beamwidth may by decreased by a directional antenna to increase gain
beamwidth
The angular coverage of an antenna beam Earth station beams are usually specified at the half-power (or -3 dB) point Satellite beams are based on the area to be covered
beamwidth
A measure, according to a standard definition, of the width of the radiation pattern of an antenna For SAR applications, both the vertical beamwidth (affecting the width of the illuminated swath) and the horizontal or azimuth pattern (which determines, indirectly, the azimuth resolution) are frequently used concepts Beamwidth may be measured in the one-way or two-way form, and in either voltage or power
beamwidth
 1  In the radio regime, of an antenna pattern, the angle between the half-power (3-dB) points of the main lobe, when referenced to the peak effective radiated power of the main lobe (188)  Note:   Beamwidth is usually expressed in degrees   It is usually expressed for the horizontal plane, but may also be expressed for the vertical plane   2   For the optical regime, see beam divergence
beamwidth
The angle of signal coverage provided by an antenna Beamwidth typically decreases as antenna gain increases
